In a young country charged with national vigour, Charu, the motherless child of a railway worker, pines for a life freed of oppressive domesticity. As diesel engines replace steam, and the calamitous churn of drought, famine, strike, chokes the railway township, she dares to imagine a different future for herself. Boarding a train she flees westwards to Bombay, even as the country rumbles towards Emergency. In the frenetic landscape of the great modern metropolis, Charu, the budding adventuress, seeks the means to live on her own terms.
